I don't wear all that much makeup as it is but on the weekends I still put on brow and eye liner, a little shadow and lip gloss but no face makeup, only moisturizer and sun screen. I have a good friend that always shows up with full makeup, lipstick, eye makeup and after our rides she looks alittle scary - lipstick and eye liner all askewed, makeup running. Bad enough so I know I don't want to look that way. If going out for a ride alone, I usually clean my face, put on sun screen and go. I think it better for the pores not to have all that makeup on.

PS: But I always wear my earrings !
